The machine is specially used for cylinder jobs, the machine has good rigidity, good accuracy. In front of the machine, installed one set double chuck clamping device and two sets ring type center rest, which is suitable for drilling drill collar.

The spindle rotate range is widely, infeeding system is driven by AC servo motor, which can be used for variously deep hole drilling process. Oil pressure fasten device and job tight adopts hydraulic device, instrument display, safe and reliable.
